VSpecification of Letters Patent No. 33,055, elated August 13, 18.61.

To all whom it may concern? Be it known that we, LYMAN SMITH, ot NorthEast, in the county of Erie and State of Pennsylvania, and ROBERTFRENCH, of

Keokuk, in the county ot'l Lee and State of Iowa, have invented certainnew and useful improvements in Apparatus for Casting Soap or otherSubstances into Balls, Cakes, or other Forms; and we do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of thisspecification,in which- Figure l is .a vertical section of the appa-Iratus. Fig. 2 isa plan of the same. j Similar letters of referenceindicate corresponding parts in both figures.

rlhis invention. relates lto the employment of a mold `or connectedseries of molds arranged one above the other, in connection with anelevated Mcistern or other reservoir from which the soap or othersubstance to be cast is forced in a liquid state into the mold by staticor mechanical pressure. j

It consists in the attachment of `the mold or series of molds to theconducting pipe connected with the elevated cistern or other reservoirby mea-ns of a spigot and faucet or other movable joint between whichand the mold or series of' molds there is a stop-cock to shut thesubstance within the mold or molds and retain the pressure therein afterthe filling thereof, and after the disconnection thereof from the pipe.

To enable others skilled in the art to make and use our invention wewill proceed to describe its construction and operation.

The apparat-us represented, is intended for the casting of transparentsoap balls. The elevated cistern A, in which the soap is brought to thedesired degree of liquidity by the combined influence of heat and theaddition of a suitable quantity of alcohol, is incased with asteam-jacket B. The conduct-ing pipe C, by which the soap is con veyedfrom the cistern A, to the mold, is permanently attached to the bottomof the cistern and is incased to the point where the bend, through whichthe soap rises to the mold, commences with a steam jacket D, which is infree communication with the jacket B. The steam is admitted to thejacket B, by a pipe a, and the water of condensation is drawn oii fromthe bottom of the jacket D, by a cock b, or steam trap.

tion turned up in an upright position and has permanently secured to itsextremitythe upright spigot c. The pipe C, is fitted at its connectionwith the cistern with a valve m.

(l, (l, are the molds of which there may be any number consisting ofcavities arranged one above the other in a box E, of cast iron, brass orother metal which is divided vertically into two equal parts, which arefitted together with ground faces or otherwise constructed or providedwith an air-tight `joint,-are connected by hinges c, whichienable themolds to be opened 'forthe removal `of the `balls or cakes-and arefurnished with hooks and staples a, or other means of securing them whenclosed. The several I molds are connected each with the one above andbelowit by a small passage j, by which the soap runs from one to anotherfrom the bottom to the top of the series. To the bottom one half of themold there is permanently attached the `faucet socket g, which is groundIto -fit air-.tight to the spigot c, and which is fitted with a stopcocklc, to open it to `the VIlowest mold d; and to the -top of the samehal-f, is permanently attached' the air chamber it, to which there is aVpassage z', from the uppermost mold. This air vessel is fitted somedistance from its top and bottom with a cock j.

F is the three-way cock fitted to the bend of the conducting pipe andhaving its passages so arranged, as indicated in Fig. 2, by dottedlines, that a communication may be established from the cistern to andthrough I the spigot c, or from the part of the pipe C, A

on either side of it to the atmosphere.

. As many mold boxes are provided for one apparatus as are necessary toprovide for the cooling of the molds to a proper degree to permit theremoval of the balls or cakes.

In the use of the apparatus the three-way cock is turned in a directionto close the part of the conducting pipe C, between it and the cisternA, and the valve m, is kept closed un'- til the contents of the cisternhave been brought to a liquid state, and a mold box E, having beenplaced on the spigot c, as shown in Fig. l, the valve m, and cocks la,and j, are opened and the cock F, turned to a position to open acommunication from the cistern to the mold box and close the pipe C,from the atmosphere. The soap then runs from the cistern through thepipe C, spigot c, and faucet socket g, into the mold box en- Theconducting pipe C, has its terminal pori tering the lowest mold andowing upward from one to the other through the passages 7, f, till allare filled and through the passage z', into the air vessel it; and assoon as it begins to flow from the cock j, the latter cock is closed andthe air which has remained in the said vessel above the said cock iscompressed by the column in the pipe C, and cistern A, to the degree dueto the height of said column. The three way cock F, is then turned to aposition to close the pipe C, to-the mold box still keeping the saidpipe closed to the atmosphere, and on the cock 7c, being closed thecharged mold box may be removed and an empty one substituted for it onthe spigot c, to be iilled in a similar manner;

The pressure due to the column in the pipe C, and cistern A, is retainedvin the molds after the removal of the mold and` as the contents of themolds contract in,

cooling the air in the chamber h, expands and forces back into the moldenough of the soap which was left in the air chamber below to keep themolds filled, and so make theV balls or cakes perfectly solid and oft-he exact form of the molds, thus obviating the difficulty encounteredin casting soap balls in the usual manner and in the apparatusordinarily employed, viz: the impossibility oi' casting them solid andof the proper shape, which renders it necessary to submit them to asubsequent turning process.

lVhen the operation of casting is at any time to be suspended for aconsiderable period the three-way cock F, is turned to a position tokeep the portion ofr the pipe between it and the cistern closed and toopen the other part of the pipe for the purpose of allowing the materialremaining in the spigot c, and portion of the pipe between it and thesaid cock to run through the said cock into a suitable receptacle placedbelow it, thus obviating the inconvenience that would occur in case ofthe said material cooling and setting in the last mentioned portion ofthe pipe. The material remaining in the other portion or" the pipe C,can also` be discharged` by turning the said. cock F, to a properposition, the valve m, having been previously closed.

Vhat we claim as our invention and desire. to ,secure by Letters Patent,is

rlhe attachment of the mold box E, to the conducting pipe C, inconnection with an elevated cistern A, or other means of giving pressureto the liquid substance, by means of a spigot and faucetr c, j, orequivalent joint which permits the removal of the said `box from thesaid pipe and between which and the said box there is a stop vcock j70,' all substantially as herein described.
